Barcelona have signed 20-year-old right-back Mike van Beijnen on a two-year deal, and put an £89million buyout clause in his contract.

The Dutch full-back arrives from Eredivisie side NAC Breda on a free transfer, and will join up with Barca's B team for the 2019/20 campaign.

Van Beijnen has also been on the books of both PSV Eindhoven and Willem II, with some reports suggesting that he is the son of new Barca midfielder Frenkie de Jong's agent Ali Dursun.

Barca B finished eighth in the Segunda Division B last season, and Van Beijnen will join a squad full of players determined to push their way into first-team manager Ernesto Valverde's plans.
